A-Live® · Liveness Detection

Is a Human or a Bot/AI Bot present?

Passive detection of a living human, read from neuromuscular micro-vibrations as the human holds the device. Presence confirmed in a second or less, with or without a challenge and no camera.

No matter how smart or well-coded a bot or AI-bot is, it has no heartbeat or “brainbeat.”
How it works

Commodity sensors

The accelerometer and gyroscope already in every phone capture the faint micro-vibrations of a hand at rest — no camera, no extra hardware.

On-device AI

A pre-trained classifier reads those micro-vibrations locally, directly from the sensor, and separates a living human from a recording, bot, or synthetic signal. No cloud, no network round-trip.

Alive or not alive

A presence decision is returned, ready to gate a login, a form, or a transaction in your own product flow.

What you get

Built to drop into what you already run.

  • A-Live® achieves over 99.3% accuracy
  • Passive — zero added friction
  • Entirely on-device
  • 0.5-1 seconds runtime
  • SDK / API — integrates into any existing login or access flow
  • Extends to laptops and consoles via the phone as a second factor
Use cases

Wherever a real human must be in the loop.

Standalone liveness

Add a human-present check inside any login or sign-up. A-Live® confirms a live person before access is granted — stopping bots from registering, posting, or scraping at scale.

Frictionless second factor

Instead of typing a code, the user is pinged on their phone and simply holds it for half a second. The same proof extends to laptops and consoles via the phone.

Legal & compliance

Establish the human provenance of digital signatures, contracts, and regulatory submissions with proof that a real person was present at the moment of signing.

Bot defense & ad integrity

Protect forms, account recovery, and high-value transactions — and verify real-human impressions so ad spend reaches people, not bot traffic.
